nEvIcE FOR CbNTROLLING THE EXHAUST or OTOR CARS AND THE LIKE.

Specification of Letters Patent.

Patented Feb. 7, 1922.

1 Application filed May 23, 1921. Serial No. 472,000.

To all whom it may concern:

Be it known that I, EDDY GAssALETTE, a

citizen of the Republic of Germany, resid-' ing at Berlin-Friedenau,Germany, have invented certain new and useful Improvements in Devicesfor Controlling the EX- haust of Motor Cars and the like, (for which Ihave filed application in Germany J an. 22, 1920, and in Great BritainMar. 28, 1921,) of which the following is a specification.

The present invention relatesto a device for controlling the exhaust ofmotor-cars and the like so that the gases can be instantaneouslydiverted, entirely or partly, into 7 the atmosphere from the car heateror from the silencer or from both if divided between the two.

The invention consists in the provision of a distributing casing havingone inlet and Fig. 2, an end View of the distributing casing as seen I,and

Fig. 3, an end view of thersame as seen from the direction ofthe arrowII.

A distributingcasing (Z has a flange c by means of which it is connectedto a flange b on the exhaust pipe a; of the motor. The casing has threeoutlets, one opening into a from the direction of the arrow pipe mleading to the heating system of the car, the second, into a pipe Zleading to the silencer, and the third, direct into the atmosphere.Leading to the outlets are three passages formed by partitions e and iwhich terminate in pivoted flap valves f' and 7s. The valve f isarranged nearer to the motor andis adapted to close either the passage gleading to the atmosphere or the passage h leading to the remainingoutlets, or to be set so as to distribute the exhaust gases between thetwo. The valve is can be set in the passage 7b so as to direct theexhaust gases either 'to the heating system or to the silencer or todistribute the same between both. It is evident that whatever theposition of the valve 1 .2, the exhaust gases can, by an adjustment ofthe valve f, be directed in an instant either wholly or partly to theatmosphere. This is often required either for reducing the resistance tothe motor or for making the motor distinctly heard in heavy traiiic.

I claim A device for. controlling the exhaust of 1 m0tor-cars and thelike, comprising a distributing caslng having one inlet for the exhaustgases and three outlets for the same,

one outlet leading to a heating system, one

to a silencer and a third to the atmosphere, and two plvoted flap valvesarranged 1n said casing, one valve belng arranged nearer the motor thanthe other and adapted to divert V the gases, wholly or partly, either tothe atmosphere'or to the other outlets, the second 'valv e being adaptedto divert the gases admitted by the first valve, wholly or partly,either to the heating system or to the silencer, substantiallyas and forthe purpose set forth. i

EDDY GASSALETTE.
